SpaceX launched a Falcon 9 rocket to deliver Koreasat-5A, a commercial communications satellite, to a Geostationary Transfer Orbit (GTO) from Launch Complex 39A (LC-39A) at NASA's Kennedy Space Center at 3:34 p.m. on 30 October 2017. Following stage separation, Falcon 9's first stage made a successful landing on the "Of Course I Still Love You" droneship stationed in the Atlantic Ocean.

Koreasat-5A is a communications satellite operated by KT SAT, South Korea's sole satellite service provider. Manufactured by Thales Alenia Space, Koreasat-5A will provide Direct-to-Home (DTH) broadcast, broadband, and backhaul services with its Ku-Band capacity. As a replacement for Koreasat-5, Koreasat-5A will expand KT SAT's coverage across Asia and the Middle East. Unlike other satellites in the Koreasat fleet, Koreasat-5A will provide maritime coverage of the Persian Gulf, Indian Ocean, South China Sea, and East China Sea.
